Description

この発明は、鉄道車両用レールの連結部(継ぎ目)を車輪が通過する際に生ずる発音を消音するための新規な機構に関する。 The present invention relates to a novel mechanism for muting the sound generated when a wheel passes through a connecting portion (seam) of a rail for a railway vehicle.

従来より、上記発音対策としては、レール端を斜方切断する方法が知られているが、本発明にて示すような消音専用の部材を用いる手段は現在のところ見当たらない。 Conventionally, as the above-mentioned sounding countermeasure, a method of obliquely cutting the rail end has been known, but at present, there is no means for using a member dedicated to muffling as shown in the present invention.

鉄道車両用レールは一般的には、断面をT字形とした棒状の鋼製品で、これを所定間隔にて二本平行に並べ、道床の上に並べられた枕木の上に犬釘などを用いて設置固定している。このレールは,車両の重量を直接に支えて車輪からの一点荷重を枕木と道床に分布するとともに、車輪を案内する役割を持っている。
このレールには種々の形があるが、多用されているのは平底レールである。
この平底レールは底部の形状が、安定しやすいように幅を広げた形状であり、レールの基本形状として国内外によく使われている。レールの標準長さは25メートルであり、多数本のレールを継ぎ目板にて接続して構成される。このレールは金属製であるために、熱による膨張や収縮が発生する。そのために、隣り合うレール端面に若干の間隙を持たせて熱による影響を防ぎ、レール敷設状態の安定を図っている。
従って、このレール端面間は数ミリメートルから十数ミリメートルほどの間隙を有している。そのために、走行車輪がこの継ぎ目に差し掛かると、ガタンゴトンというジョイント音が発生して耳障りである。
本発明は以上に鑑み、既設のレールをそのまま用いて、上記ジョイント音を解消することのできる、新規かつ有用なる手段を提供することを目的として発明されたものである。
Rails for railroad cars are generally rod-shaped steel products with a T-shaped cross section, two of which are lined up in parallel at predetermined intervals, and a spike is used on the sleepers lined up on the trackbed. It is installed and fixed. This rail directly supports the weight of the vehicle and distributes the one-point load from the wheels to the sleepers and the trackbed, and also has the role of guiding the wheels.
There are various shapes of this rail, but the one that is often used is the flat bottom rail.
The shape of the bottom of this flat bottom rail is widened so that it is easy to stabilize, and it is often used in Japan and overseas as the basic shape of the rail. The standard length of the rail is 25 meters, and it is composed of a large number of rails connected by a seam plate. Since this rail is made of metal, it expands and contracts due to heat. Therefore, the end faces of adjacent rails are provided with a slight gap to prevent the influence of heat and to stabilize the rail laying state.
Therefore, there is a gap of several millimeters to a dozen millimeters between the end faces of the rails. Therefore, when the traveling wheel approaches this seam, a rattling joint noise is generated, which is jarring.
In view of the above, the present invention has been invented for the purpose of providing a novel and useful means capable of eliminating the above-mentioned joint sound by using the existing rail as it is.

課題を解決する手段として本発明は以下の構成とした。
すなわち、正面視長方形状で有孔であるとともに段部を有する板体による板状部を設け、該板状部の正面視中央に、鉄道車両の車輪フランジの輪荷重を受けるための受圧部を突設し、該受圧部上面をゆるやかな曲面形状に形成する。
本発明は以上の構成よりなる鉄道車両用レール連結部消音機構である。
The present invention has the following configuration as a means for solving the problem.
That is, a plate-shaped portion made of a plate body having a rectangular shape with holes and a step portion is provided in the front view, and a pressure receiving portion for receiving the wheel load of the wheel flange of the railway vehicle is provided at the center of the plate-shaped portion in the front view. It is projected so that the upper surface of the pressure receiving portion is formed into a gently curved shape.
The present invention is a rail connection silencer mechanism for a railway vehicle having the above configuration.

本発明によれば、レール側面に本品を設けることにて、レール継ぎ目箇所内方の受圧部が張り出し、車輪のレール継ぎ目位置通過時に車輪フランジ下端にてこの受圧部上面に荷重がかかるので、従来のジョイント音を極小とすることのできる有用なる手段を得ることができる。また、受圧部上面にゆるやかな凸状曲面を採用することにて、レール継ぎ目箇所通過時にスムースな車輪移動を行うことができる。本品はシンプルな構成にて製作コストの面での有利性を有するものである。 According to the present invention, by providing this product on the side surface of the rail, the pressure receiving portion inside the rail joint portion protrudes, and when the wheel passes through the rail joint position, a load is applied to the upper surface of the pressure receiving portion at the lower end of the wheel flange. It is possible to obtain a useful means capable of minimizing the conventional joint sound. Further, by adopting a gentle convex curved surface on the upper surface of the pressure receiving portion, it is possible to smoothly move the wheels when passing through the rail joint. This product has an advantage in terms of manufacturing cost with a simple structure.

以下、本発明の実施形態について説明する。
図において、1は段部を有する板体による板状部で、レールの腹部にぴったりと当接する断面形状を有して、従来から用いられている継ぎ目板と同等の長さを有する。2は取付孔で、板状部適所に4個が穿設され、その孔位置は既存の継ぎ目板と同等である。
3は受圧部で、上記板状部と一体に形成される部分である。この受圧部は図2および図7にて示すように、正面視において曲面状側面を有して山形に形成され、受圧部底面4と、緩やかな曲面状の受圧部上面5とを有している。側面からみると、受圧部底面から上方へ向かうにつれて外方に向かう曲面部6を有し、また前記板状部上面近傍部分には段部7が設けられている。以上の各部は実線で記入してあるが、一体部品の鋼製鍛造品である。
(図3参照)
Hereinafter, embodiments of the present invention will be described.
In the figure, reference numeral 1 denotes a plate-like portion formed of a plate having a step portion, which has a cross-sectional shape that closely contacts the abdomen of the rail, and has a length equivalent to that of a conventionally used seam plate. Reference numeral 2 denotes mounting holes, four of which are bored in appropriate positions on the plate-shaped portion, and the positions of the holes are the same as those of the existing seam plate.
Reference numeral 3 denotes a pressure receiving portion, which is a portion integrally formed with the plate-shaped portion. As shown in FIGS. 2 and 7, the pressure receiving portion has a curved side surface in a front view and is formed in a chevron shape, and has a pressure receiving portion bottom surface 4 and a gently curved pressure receiving portion upper surface 5. There is. Seen from the side surface, it has a curved surface portion 6 that goes outward as it goes upward from the bottom surface of the pressure receiving portion, and a stepped portion 7 is provided in the vicinity of the upper surface of the plate-shaped portion. Each of the above parts is marked with a solid line, but it is a forged steel product that is an integral part.
(See Fig. 3)

次にレール13の構造について説明する。図4にて示すように、断面略逆T字形の物品で、断面略長方形状の頭部10と、所定幅の腹部11,平板状の底部12が一体に形成された物品で、各所に適宜に勾配や面取りを有している。
前記の受圧部は図のごとくレール側面に当接して位置し、レールに取付孔2を介してボルトとナットにて螺着締結される。車輪20は図のごとくレール頭部上面を走行し、継ぎ目位置に差し掛かるとフランジ下面は、前記の受圧部上面に移動して車輪20は頭部10に乗り移る。従って、従来のジョイント音発生は極小となるのである。
以上を図10〜図11を用いて説明する。
Next, the structure of the rail 13 will be described. As shown in FIG. 4, it is an article having a substantially inverted T-shaped cross section, in which a head 10 having a substantially rectangular cross section, an abdomen 11 having a predetermined width, and a flat bottom 12 are integrally formed. Has a slope or chamfer.
As shown in the figure, the pressure receiving portion is located in contact with the side surface of the rail, and is screwed and fastened to the rail via a mounting hole 2 with bolts and nuts. The wheel 20 runs on the upper surface of the rail head as shown in the drawing, and when the joint position is reached, the lower surface of the flange moves to the upper surface of the pressure receiving portion, and the wheel 20 moves to the head 10. Therefore, the conventional joint sound generation is minimized.
The above will be described with reference to FIGS. 10 to 11.

図10は従来のレール継ぎ目機構の説明図である。
上図は車輪が継ぎ目に差し掛かる直前状態で、車輪はレール頭部上面に輪荷重を伴い走行している。中図は、車輪が継ぎ目位置に差し掛かった状態である。車輪下端はまず走行レール頭部よりやや下方に移動し、対向するレール頭部端に衝突する。このときにジョイント音が発生する。次に、車輪下端は次のレールに乗り上げ、(下図)そのまま走行し、これをくり返すことにて、一定の時間間隔にてジョイント音が発生する。
図11は本発明の場合である。
上図は通常走行状態である。中図では、車輪フランジが本発明の受圧部上面に輪荷重がかかり、走行車輪は従来時のような下方移動(落ち込み)はなく、また次のレール頭部端への衝突も発生せず、従ってジョイント音も発生しない。この位置を走行通過すると、次のレールにスムースに移行する。(下図)従って、本発明使用にて、ジョイント音の発生を回避することができる。
なお、図12から図14において、Aは車輪下端とフランジ下端との距離寸法、Bはレール頭部上面から受圧部上面までの距離寸法、Cは本発明の受圧部最突出位置と段部との距離寸法(幅)、Dは受圧部の長さである。AとBの高さ(寸法)は等しいかもしくはAよりBが大であることおよびCの寸法はレール幅以上であることが必要である。
図9は本発明の他例を示すもので、受圧部の上部中央に受圧部材8を焼きばめ方式にて挿入固定したものである。図に示すごとく、受圧部上部にアリミゾ形の凹部を設け、該凹部と同形でわずかに大きいサイズの鋼材を設けたものである。この受圧部材は車輪フランジを守るため、該フランジよりも柔らかい材質とする。
また,受圧部材は上下寸法を高めとし、叩き込んだ後にサンダーでレール上面との高さ調整を行う。受圧部材中央には雌ネジ9が刻設される。この雌ネジは、受圧部材の離脱時のためのもので、この雌ネジを利用してプーラーやスターチングハンマーを用いて離脱を行うことができる。
FIG. 10 is an explanatory view of a conventional rail seam mechanism.
The figure above shows the state just before the wheels reach the seam, and the wheels are running with a wheel load on the upper surface of the rail head. The middle figure shows the state where the wheels are approaching the seam position. The lower end of the wheel first moves slightly below the head of the traveling rail and collides with the end of the head of the opposite rail. At this time, a joint sound is generated. Next, the lower end of the wheel rides on the next rail, runs as it is (see the figure below), and repeats this, so that a joint sound is generated at regular time intervals.
FIG. 11 shows the case of the present invention.
The above figure shows the normal running state. In the middle figure, the wheel flange applies a wheel load to the upper surface of the pressure receiving portion of the present invention, the traveling wheel does not move downward (fall) as in the conventional case, and the next rail head end does not collide. Therefore, no joint sound is generated. After passing through this position, it smoothly shifts to the next rail. (Figure below) Therefore, by using the present invention, it is possible to avoid the generation of joint sound.
In FIGS. 12 to 14, A is the distance dimension between the lower end of the wheel and the lower end of the flange, B is the distance dimension from the upper surface of the rail head to the upper surface of the pressure receiving portion, and C is the most protruding position and the step portion of the pressure receiving portion of the present invention. Distance dimension (width), D is the length of the pressure receiving portion. The heights (dimensions) of A and B must be equal or B is greater than A and the dimension of C must be greater than or equal to the rail width.
FIG. 9 shows another example of the present invention, in which the pressure receiving member 8 is inserted and fixed in the upper center of the pressure receiving portion by a shrink fitting method. As shown in the figure, an armizo-shaped recess is provided in the upper part of the pressure receiving portion, and a steel material having the same shape as the recess and slightly larger in size is provided. In order to protect the wheel flange, this pressure receiving member is made of a material softer than the flange.
In addition, the pressure receiving member has a higher vertical dimension, and after being struck, the height is adjusted with the upper surface of the rail with a sander. A female screw 9 is engraved in the center of the pressure receiving member. This female screw is for detaching the pressure receiving member, and can be detached by using a puller or a starting hammer using this female screw.

以上、本発明について記したが、本発明は既述のようにレール継ぎ目箇所における車輪の落ち込みとレール端への衝突を防いでジョイント音の発生を防止できるものである。
受圧部上面はゆるやかな凸状湾曲面であり、その最高高さをレール頭部上面と同一もしくは近似とすることにて、スムースな車輪通過を可能とし、また上記のごとく曲面のために、なめらかな車輪移動が可能となる。
なお、受圧部は側面視において、レールの内側方向へ張り出しているが、これは車両走行時における車輪のレールに対する横ぶれに対応したものである。
既述構成のように、本発明では車両荷重はまずレール頭部上面にて支えられ、継ぎ目位置ではフランジが受圧部上面に当接することによって、この受圧部にて支え、通過後は再びレールにて支えるという仕組みにてジョイント音を防止することができる。
受圧部上面長(図14のD)はレール端面間隙の約3倍以上が好ましく、これにて機能的安定性が保たれる。なお、受圧部と反対側のレール腹部には通常の継ぎ目板が用いられて、ボルトとナットにて螺着締結される。また、本発明にて例示したレール断面形状は一例であって、他形状のレールの場合は,そのレール形状に合わせて適宜に板状部等の変更が必要である。以上のごとく、本発明によってジョイント音の発生を防止でき、かつ車輪の落ち込みのないスムースな省エネ的な走行を得るための有用なる手段を得ることができる。
As described above, the present invention has been described, but as described above, the present invention can prevent the wheels from falling at the rail joints and colliding with the rail ends to prevent the generation of joint noise.
The upper surface of the pressure receiving part is a gently convex curved surface, and by making the maximum height the same as or similar to the upper surface of the rail head, smooth wheel passage is possible, and due to the curved surface as described above, it is smooth. Wheel movement is possible.
The pressure receiving portion projects inward of the rail in the side view, which corresponds to the lateral movement of the wheel with respect to the rail when the vehicle is running.
As described above, in the present invention, the vehicle load is first supported by the upper surface of the rail head, and at the seam position, the flange abuts on the upper surface of the pressure receiving portion to support the load, and after passing, the rail is again supported. Joint noise can be prevented by a mechanism that supports the rail.
The length of the upper surface of the pressure receiving portion (D in FIG. 14) is preferably about 3 times or more the gap between the rail end faces, whereby functional stability is maintained. A normal seam plate is used for the abdomen of the rail on the opposite side of the pressure receiving portion, and the rail is screwed and fastened with bolts and nuts. Further, the rail cross-sectional shape exemplified in the present invention is an example, and in the case of a rail having another shape, it is necessary to appropriately change the plate-shaped portion or the like according to the rail shape. As described above, according to the present invention, it is possible to obtain a useful means for preventing the generation of joint noise and obtaining smooth and energy-saving running without the wheels falling.
